“…For the monitored location on the tooth surface, there was no noticeable strain variation before the crack occurred on root surface. However, at a certain point along the crack growth path, the stress increased as the crack tip approached that point and decreased as the crack tip moved away from it [20,21], as illustrated in Figure 9c. For the initial crack formed near the monitored position, the stress/strain was decreasing during the crack extension process, as illustrated in Figure 9b.…”

The tooth bending fatigue fracture is caused by the alternating loads for the heavy-duty transmission gears. The crack initiation and propagation are the two major parts in the failure process. The crack propagation behavior is mainly affected by initial crack position except for the load and material properties. In this paper, the crack propagation model of a gear is established under the considering of crack initiation location by using extended finite element method (XFEM). The model accuracy is verified by testing results of strain and fractography by conducting the single-tooth bending fatigue experiment. The influence of crack initiation locations on subsequent crack propagation behavior is analyzed. The crack length in the tooth width direction and depth direction is faster when the initial crack is located in the middle of root surface. The crack growth rate is lower for the initial crack located in the surface close to the end surface of the gear.
